Quote I found online from a arb rep...
Hi guys, most of you will be aware that ARB was a pioneer amongst aftermarket manufacturers when we performed actual crash testing on a 100 Series LandCruiser back in 1997, in order to prove the air bag compatibility of our bars.
Some 17 years on, I think most of you would be interested to know that we recently purchased a brand new Ford Ranger, fitted an ARB bar and handed it over to ANCAP for testing. You’ll be pleased to know that results proved the fitting of the ARB deluxe combination bar did not affect the ANCAP 5 star rating of the PX Ranger for occupant protection.
Whilst this is obviously not directly relevant to the FJ Cruiser, it certainly highlights the lengths we go to to ensure our bars meet or exceed all of the relevant design and safety requirements in Australia. As has been mentioned, this is an expensive exercise considering the cost of both the vehicle and the testing.
For those of you with an appetite for detail, please read on regarding the current requirements for ANCAP, Australian Standards, Australian Design Rules and air bag compatibility, and how ARB addresses each category.
The Australasian New Car Assessment Program run by ANCAP Australasia Ltd performs crash tests and new vehicles are awarded or deducted points based on a combination of test categories and scientific criteria. All vehicles are assessed under identical testing standards and conditions. Following crash tests, data is gathered and assessed using internationally recognised protocols and star-ratings are determined for the vehicle. Points are also awarded if the vehicle is fitted with safety features such as Anti-lock Braking System (ABS) Electronic Stability Control (ESC) and seat belt reminders.
Vehicles are usually tested by ANCAP in their production line condition and without accessories such as bull bars. Due to the publicity around the possible but untested effect bull bars may have on ANCAP ratings, ARB as a market leader, has taken the step of submitting a vehicle fitted with an ARB bull bar to ANCAP for testing to ensure compatibility. ANCAP only rates the safety of vehicles. As a vehicle accessory, the bull bar itself is not approved or rated by ANCAP. ANCAP’s testing demonstrated that the fitment of the ARB bull bar did not affect the vehicle’s 5 Star ANCAP rating.
Australian Standards and Australian Design Rules
ARB bars are specifically designed to comply with relevant Australian Design Rules (ADR) and Australian Standard AS4876.1-2002.
The objective of the standard is to provide manufacturers with performance requirements for Vehicle Frontal Protection Systems (VFPS) and address issues including:
• Applicable ADR requirements
• Road user protection requirements
• Test method, marking and packaging
AS 4876.1-2002 does not address the issue of VFPS compatibility with Vehicle Occupant Protection Systems (eg air bag triggering). The Standard applies to the design and construction of VFPS for motor vehicles up to and including 3500kg GVM covering a number of different categories.
Introduced September 2002 the first Australian Standard for Motor Vehicle Frontal Protection Systems was published. A bull bar that complies with the standard has been designed to offer at least a minimum degree of protection to road users, including pedestrians, cyclists, motorcyclists and other vehicle occupants. The Standard is applicable to VFPS for new model vehicles first produced after 1st January 2003.
• Lighting regulations eg the bull bar must not obscure the headlights or any other external lighting
• Occupant crash protection regulations
• Sharp edges and protrusions. Also influenced by individual state roadworthy regulations
• Anchorages / fitment
• Design and profile
• ADR 42 External or Internal Protrusions. ADR 69 full frontal impact occupant protection
• ADR 72 dynamic side impact occupant protection
• ADR 73 offset frontal impact protection
Air Bag Compatibility
With an air bag equipped four wheel drive vehicle, it is essential that the vehicle's crush rate and air bag triggering is not altered when a bull bar is installed. ARB assesses each vehicle's frontal crush characteristics and replicates the crush rate into the design of each air bag compatible bull bar and its mounting system. This method enables engineers to achieve maximum possible vehicle and passenger protection without affecting the crash pulse. ARB has invested heavily in vehicle crash barrier tests to validate the performance and compliance of its air bag compatible bull bars.
Vehicles fitted with an airbag (or manufactured to comply with ADR 69 - Full Frontal Impact Occupant Protection or both ADR 69 and ADR 73 - Offset Frontal Impact Protection) can only be fitted with a bull bar which has been demonstrated by the bull bar manufacturer not to adversely affect compliance with the ADRs or interfere with the critical air bag timing mechanism. ARB’s bull bars meet these requirements.
In Summary, with an ARB bar fitted to a modern vehicle, you have the best of both worlds, with vastly better protection in animal impacts, plus the security of knowing that the vehicle’s intrinsic safety in severe accidents is not compromised.
